Dylan needs to buy new contact lenses. His ophthalmologist sells 8-lens boxes in packs of 2 for $52 & 10-lens boxes in packs of 4 for $120. Which option is a better buy?

no

step-by-step explanation:

2 1/2 feet

step-by-step explanation:

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
